The strongest evidence is a specific statement from the publisher or developer about the trailer itself, supported where possible by provenance information from the original file. Visual oddities, missing metadata, and detector results are not proof on their own.
Start with a disclosure about the trailer itself
Find the trailer on the publisher’s or developer’s official channel and check its description. Look for a clear statement about whether generative AI was used to create or edit the trailer’s imagery, video, audio, or other elements.

Specificity matters. A statement that a studio uses AI somewhere in development does not establish that a particular trailer contains AI-generated material. Likewise, “Made with AI” may leave unclear whether the asset was generated in full or only edited with generative tools. C2PA guidance says source disclosures should “objectively describe the core processes involved in the creation of an asset.” C2PA’s user experience guidance explains why a useful disclosure should make the extent of AI involvement clear.
Check for a matching explanation in an official developer statement, press kit, or production account. Compare what each source actually says: a general statement about AI use is not the same as an explicit disclosure about this trailer.
Check provenance information in the original file
If the publisher offers a downloadable original, inspect it for C2PA Content Credentials or other provenance information. Content Credentials can record claims about an asset’s origin and history. Review what the credential says and who signed it; C2PA’s trust model ties a credential to the identity associated with its signing key. The C2PA technical specification describes this provenance system.
A credential is not automatically an AI label. C2PA credentials can record provenance for media made without generative AI, too. Nor does a credential prove that every claim about an asset is true: it shows the recorded information and its associated signer.
Credentials may not be available in every video format or survive every upload and editing workflow. A missing credential therefore does not establish that a trailer was made without AI. When possible, check the original downloadable file rather than assuming a social-platform copy preserves all embedded information.
Treat visual clues and detector results cautiously
There is no established visual checklist that reliably identifies generative AI in game trailers. An unusual frame or detail can be a reason to investigate, but appearance alone does not establish how it was made. Compositing, compression, motion blur, animation, stylization, and ordinary editing can all affect what viewers see.
Automated checkers are limited by what they are designed to recognize. OpenAI says its provenance signals may be unavailable or degraded and are not designed to detect content from other AI models. Its verification applies to supported OpenAI signals in supported images and audio, not arbitrary game-trailer video. A positive result is therefore narrow evidence about supported provenance; a negative result cannot rule out AI use. OpenAI also cautions that provenance signals do not establish accuracy, legal ownership, editing history, or context. See its documentation on provenance signals.

A platform disclosure is evidence that should be interpreted according to that platform’s rules, not treated as a forensic finding about a trailer. YouTube’s guidance on disclosing altered or synthetic content describes disclosure expectations and distinguishes them from some production assistance, such as using generative tools to help create or improve an outline, script, thumbnail, title, or infographic.
A PC Gamer report dated January 16, 2026, described a change to Steam’s disclosure form focused on AI-generated assets used in marketing or content consumed by players, rather than efficiency uses of AI tools behind the scenes. That is secondary reporting; consult the report and Valve’s current developer documentation before stating Steam’s rule as current policy.

Quick Recap
How to report what you found
- Identify the exact asset. Use the official trailer or original downloadable file, not an edited repost, and note where it was published.
- Look for a specific disclosure. Record whether the publisher or developer says generative AI was used in this trailer, and which parts or production steps it describes.
- Check corroborating records. Compare the statement with any official production account and, if available, the original file’s provenance information and signer.
- Keep tools within scope. Before relying on a checker, confirm which file types and signals it supports. Do not treat an unsupported or negative result as a clean bill of health.
- State the evidence level accurately. If there is no direct confirmation, say the production method could not be verified. Describe a suspicious detail as an observation or question, not as proof of AI use.
